Isaac Hull (March 9, 1773 – February 13, 1843) is a Commodore in the United States Navy.
He commands several famous U.S. naval warships including USS Constitution ("Old Ironsides") and sees service in the undeclared naval Quasi War with the revolutionary French Republic (France) 1796–1800; the Barbary Wars (1801–1805, 1815), with the Barbary states in North Africa; and the War of 1812 (1812–1815), for the second time with Great Britain.
In the latter part of his career he is Commandant of the Washington Navy Yard in the national capital of Washington, D.C., and later the Commodore of the Mediterranean Squadron.
For the infant U.S. Navy, the battle of USS Constitution vs HMS Guerriere on August 19, 1812, at the beginning of the war, is the most important single ship action of the War of 1812 and one that makes Isaac Hull a national hero.
